BASIC display variables: While MM local basic programs are not specifically listed in the documentation on the RAM residence list 30/70-5320), they can be entered as local functions in the residence list without any particular restrictions.

Problems "Residence list where there is no MM redundancy" resolves the following:

Redundancy If mass memory redundancy is not implemented, the system’s operator function fails in the event of a mass memory error.

Cause The underlying cause is:

No access to the system list If the single hard drive fails, access to the system list is impossible. This means that display and operating procedures are blocked.
